Embodiment 1
[0068] Determination method of carbohydrate components in compound salvia miltiorrhiza extract:
[0069] Determine according to high performance liquid chromatography (Appendix VI D of Chinese Pharmacopoeia 2010 edition).
[0070] The chromatographic conditions and system suitability test used PrevailTM Carbohydrate ES chromatographic column, with acetonitrile as mobile phase A, water as mobile phase B, flow rate 0.8ml / min, column temperature 30°C; WATERS 2420ELSD detector was used for detection, and the parameter was set to gain 10. Air pressure 25psi, drift tube 60°C, Neb heater: 60%. The number of theoretical plates should be no less than 4000 based on the chromatographic peak of sucrose, and the chromatographic resolution of fructose and glucose should be no less than 2.0.
